I'm trying to unravel the WVO system that is on the X I purchased and since I don't know how an oem PSD is plumbed I was hoping for a diagram from someone. Mostly interested in how the fuel lines come into the oem filter head and where they go from there. That and how the returns are plumbed. I'm trying to figure out if my loop is full or partial, etc.

Thinking of adding a controlled loop via 3 way valve...
